1. A controller, comprising logic, at least partially including hardware logic, configured to: receive a predetermined reload rate parameter and a save rate parameter from a memory location; generate a first set of repeating pseudo-random patterns by reloading a first seed according to the predetermined reload rate parameter; and transmit the first set of repeating pseudo-random patterns on a first lane of a communication interconnect, wherein the logic is further configured to save the first seed in accordance with the save rate.
A controller system is designed to enhance data transmission security and reliability in communication interconnects by generating and transmitting repeating pseudo-random patterns. The system addresses the need for secure and controlled data transmission in high-speed communication links, where predictable or static data patterns can be vulnerable to interception or interference. The controller includes hardware logic that receives configuration parameters, including a reload rate parameter and a save rate parameter, from a memory location. These parameters dictate how frequently the system reloads a seed value to generate new pseudo-random patterns and how often the seed is saved for future use. The controller generates a first set of repeating pseudo-random patterns by reloading a first seed according to the specified reload rate. These patterns are then transmitted on a first lane of a communication interconnect. The seed is saved at intervals defined by the save rate parameter to ensure continuity and consistency in pattern generation. This approach allows for controlled, repeatable pseudo-random data transmission, which can be used for testing, encryption, or error detection in communication systems. The hardware-based implementation ensures low-latency and high-performance operation, making it suitable for high-speed interconnects.
2. The controller of claim 1 , wherein the logic is configured to: generate a first pseudo-random pattern; and repeat a subset of the first pseudo-random pattern in accordance with the predetermined reload rate parameter; and transmit the subset of the pseudo-random pattern on the communication interconnect.
A controller for managing communication on an interconnect system addresses the challenge of efficiently transmitting data while maintaining signal integrity and minimizing interference. The controller includes logic that generates a first pseudo-random pattern, which is a sequence of data designed to reduce electromagnetic interference and improve signal quality. To optimize transmission, the logic repeats a subset of this pseudo-random pattern at a predetermined reload rate, ensuring consistent and controlled data flow. The subset is then transmitted over the communication interconnect, which may be a bus or other data transmission medium. This approach allows for flexible and adaptive data transmission, balancing performance and reliability. The pseudo-random pattern and its repetition help mitigate issues like signal distortion and crosstalk, which are common in high-speed communication systems.
